Application To all whom it may concern.-

Be it known that l, Gns'rsv :BEKNHARD Persons, a subjectof the Emperor of many, residing in the oily d Philadelphia, in the State ol Pennsflv have invented certain new and i proveinents in Ges-fiictuatcd in" gines or Compressors, of which tln is a true and exact description 1' ing had to the accompanying rawin forin part thereof.

My invention. relates to 0O1D or blowing engines which are actuated l engines, andhas for its object to p governorsystem for the control. oi engine b" which it is se ne" der- ln blowing engi gas engines, and i. flexible than where the engine a steam engine, the rise in pressure ceiver of the hlowii'rg engine has given. l considerable trouble, and, to enable tin a D en ine to work under such conditions, L116 b A. I plan has been devised oi so varyni the motions of the an admission valve or the coinressor that when the nessure inthe 1;..1'. admission valve is delayed so that the q unntity of air cmnpressed at each stroke of the engine lS L' iIDlIIlSlIGL -H This, howe r, ohviously diminishes the efficiency oi the 011-- gine, and it is exceedingly sonic means should h. pm under similar conditions, the gas be capable of working with greate and it is particularly to secure result/that n'iy invention is if particular form disclosed ol' the novel inc: for accomplishing this result which devised comprises the :.:om.hination in an engine of the kind described of cylind,

The device for operating and for varying the motions of the admission valve of the compressor consisting of the link F having its upper end guided on an adjustable support such as f", forms the subject matter of control the exit valve of as in the present case it pressure cylinder I.

control my application for Letters Patent, filed, April 22nd 1903-Serial Number 153,775 though in my said former application the adjustment of the bearing f was accomplished by means acting directly upon it and independent of the impulses it by the motions of the link Ff. Inmy other application filed September 3rd 1903 Serial Number 171,763 I have shown and dc scribed a device consisting of the fluid cylinder G, and the piston G, said piston bein attached' to a movable art of an engine, W 'ch movable part is, in the operation of the enine, givcnalternating impulses in opposite irectrons and connected to vary the operations of one oiymore elements oi the engine.

As in the resent case, the connection is with the lever from which connections are made to the link F the adjustable weight J, on the gas engine governor, and the gate or valve ing the cooling water-which jackets the gas engine cylinder, and my said last mentioned application claims broadly the employment of the cylinder for such purposes as also the use of a governing device to the fluid c linder G, is control ed by the It will be understood. thatunder normal conditions of pressure the valve G, closes both of the exit orts of the cylinder G, the

iston G, being held stationary in the cyliner and through its connection with the lever F holding such lever stationary, as also the attached bearing f, on the short arm of that lever. Under these conditions the mo tion of the link F", and the attached admission valve is constant, the weight J remains j in the conduit B",

rises above normal, the said in a fixed position v.on the lever L and the gate or valve J remains in a fixed position consequently the o ,eration of-the gas engine is controlled sole y by the governor L, which, through the described mechanism, determines the cut off of the valve, admitting air and gas to the cylinder, while the cooling Water passing through the is of conhowever the presof the compressor ressure is comstant Volume. In case, sure 1n the recelver E,

v municated through the pipe to the cylinder I, and moves the piston cylinder, until the increased neath the piston is balanced by H up in the given to V the cylinder G.

pressure be cylinder 1, falls, the the compresl sion of the spring 1 This upward motion of the iston carries with it the attached end of the ever H, which, turning on its attachment to the link H, raises, through'rod H the valve G opening the lower exit port of The piston G, is then free to move down under the recurring downward impulses communicated to the lever F, by its connection with the link F fluid flowing in through the upper admission port of the cylinder G, at each don "award movement and the motion continuing until the corres ending downward movement of the link 1, causes the valve G to again close the lower exit port when the piston G, and connected parts are again. brought to a sta- ,tion'ary position; but the downward motion of the lever F is of course accompanied by an n nvard motion of the upper lever arm F, and earing nin f in consequence of which the motion 0' the link F is so varied as to defer the ciosin of the admission valve connected with the valve stem F, so thata.

smaller volume of air is compressed at each stroke of the piston in the compressing cylinder and consequently the gas engine running with uniform 7 this diminished quantity of air to the increased pressure temporarily existing in the I'GCGIVGI', but it is evident that this capacity of the gas engine to work under the abnormal conditions mentioned is secured by serious loss in the volume of air compressed and therefore I provide for so'deferring the cut oil of the gas engine admission valves that under these conditions a larger quantity of the expansive mixture is admitted to the cylinder and its capacity for work thereby increased. This is accomplished by the action of the downwardly moving lever F", on the rock shaft J shifting said rock shaft so that through its connection J and link J, it moves the adjustable weight J", out toward the outer end of the lever L thus increasing the load on the governor L, and insurin that under the same speed the stop lever M will be retracted so as to defer its contact with the hook catch N that is, so that the valves P and P, will remain )en. longer and admit a greater volume of t e expansive gases to the engine cylinder. In effect, this increases the speed of the engine and makes it desirable to provide an increased quantity of water for cooling the cylinder, and the same niotionol the rock slialt J which affects the cut off of the gas engine retracts the val ve J, increasing the how of water through the water jacket. Of course where the suoply of water to the water jacket is directly controlled by the speed of piston movement this governing device would be unnecessary.

It will readily be seen that when the pres sure in the receiver of the engine and in the effect upon the exit valve of the cylinder G, will'be directly the power is enabled to compress Y dovmwarcl to open the to move upward, and

.pressoi' or blower one &

reverse of that desciihcd, the valve moving upper exit port whereupon the impulses cornniunicstedto the lever F will ceuseit and the piston G, will eil'ect the shifting: of the parts connected to the love; F, in the opposite direction to thst already descrihcxi.

Having now described my invention, Wh at I claim as new and desire to secure by Letters Patent is l.
